2017-09-27IB/hfi1: Extend input hdr tracing for packet typeMike Marciniszyn
The etype field from the rhf can have more values than just IB and BYPASS. Extend the current tracing to report a symbolic for the etype field for non-bypass packets. Bypass packets will continue to report the l2. As part of this fix the etype and the l2 are added to the tracing struct and are available for trigger and filter operations.

2017-09-27IB/hfi1: Unsuccessful PCIe caps tuning should not fail driver loadHarish Chegondi
Failure to tune PCIe capabilities should not fail driver load. This can cause the driver load to fail on systems with any of the following: 1. HFI's parent is not root. Example: HFI card is behind a PCIe bridge. 2. HFI's parent is not PCI Express capable. In these situations, failure to tune PCIe capabilities should be logged in the system message logs but not cause the driver load to fail. This patch also ensures pcie capability word DevCtl is written only after a successful read and the capability tuning process continues even if read/write of the pcie capability word DevCtl fails.

The patch simplifies mlx5_ib_cont_pages and fixes the following issues in the original implementation: First issues is related to alignment of the PFNs. After the check base + p != PFN, the alignment of the PFN wasn't checked. So the PFN sequence 0, 1, 1, 2 would result in a page_shift of 13 even though the 3rd PFN is not 8KB aligned. This wasn't actually a bug because it was supported by all the existing mlx5 compatible device, but we don't want to require this support in all future devices. Another issue is because the inner loop didn't advance PFN so the test "if (base + p != pfn)" always failed for SGE with len > (1<<page_shift).

2017-09-25IB: Correct MR length field to be 64-bitParav Pandit
The ib_mr->length represents the length of the MR in bytes as per the IBTA spec 1.3 section 11.2.10.3 (REGISTER PHYSICAL MEMORY REGION). Currently ib_mr->length field is defined as only 32-bits field. This might result into truncation and failed WRs of consumers who registers more than 4GB bytes memory regions and whose WRs accessing such MRs. This patch makes the length 64-bit to avoid such truncation.

2017-09-25IB/core: Fix typo in the name of the tag-matching cap structLeon Romanovsky
The tag matching functionality is implemented by mlx5 driver by extending XRQ, however this internal kernel information was exposed to user space applications with *xrq* name instead of *tm*. This patch renames *xrq* to *tm* to handle that.
